Modular Action Wrench from Short Action Customs

I very frequently use a variety of Short Action Customs (SAC) equipment in my gunsmithing shop and on the channel. I often use one action for multiple barrels, so a barrel vise and action wrench are everyday must-haves for me.

About the Short Action Customs Modular Barrel Wrench

I typically use several different action wrenches. 

I have a few of the external style, which I use for really heavily torqued-on actions, especially factory actions. Overall, I prefer the internal style, but with one for each action type – it can get expensive and take up considerable space.

Short Action Customs has come out with a modular system that utilizes the internal services of the receiver to tighten the receiver onto the barrel. It has a bumper on the end that protects the end of the barrel and inside of the action. There are a variety of heads for different action types. This wrench is limited to 120 foot pounds. I torque down to 90 foot pounds, so I’m well in range. 

From Short Action Customs: 

MODULAR ACTION WRENCH… THE ONE TO RULE THEM ALL!!!

Like all of our Original Products at Short Action Customs, the Modular Action Wrench was born out of necessity. After spending over $1500 in action wrenches that were marginal at best, we decided to create a complete modular system that offers a very low cost of ownership, yet offers a precise fit to your specific action. Best yet, all parts are covered by our lifetime guarantee (see details below). 

THE KIT INCLUDES ONE ACTION WRENCH HEAD OF YOUR CHOICE. CLICK HERE TO PURCHASE ADDITIONAL HEADS IF NEEDED.

The Modular Action Wrench is a modular system composed of a few parts.  

WRENCH BODY:

After extensive torture testing we manufactured our wrench bodies out of 4140 Alloy Steel with a super hard heat treat and protected with a Black Oxide finish. With our unique modified 3/8″ square drive interface is tool-less and offers super quick wrench head changes. On the back end, we have a standard 5/8″ Hex to work with any standard 6 point or 12 point socket. With a nominal .685″ body diameter, it works with a large array of actions from Howa 1500’s, Tikka T3’s to the Surgeon XL magnum action.

WRENCH HEAD:

The heart of our system. The action wrench heads are quickly secured to the wrench body with out the use of tools.  Each action wrench head is designed to properly fit specific actions ensuring proper torque transfer to the action with out any damage.  Most of the action wrench heads are Wire EDM cut to a .001″ tolerance out of 4140 Alloy Steel, then heat treated to HRC 32 to be softer than the action, yet standing up to abuse. Finally we finish the action wrench heads with a corrosion resistant Black Oxide finish to ensure a long service life.

One of the best features of our action wrench heads is that they work with most 3/8″ Square Drive Extensions that are currently available on the market. 

FRONT BUMPER:

At the very front of the Modular Action Wrench assembly is our front bumper. Made in two lengths for barrels with counterbores and with out counterbores. Made of super strong Delrin, the front bumpers main purpose is to properly secure the action wrench head to the body via a 8/32 thread. Secondly, the front bumper properly locates the action wrench assembly into the action, ensuring that the head is precisely in the correct spot to prevent any damage to the action. Lastly, the front bumper protects the face of the barrel. It never made sense to us at Short Action Customs why people insert hard, steel objects and press them up against the face of the barrel.

Simply select the appropriate model number for the action you wish to use. If you do not see your action listed, please contact us, we are always developing new action wrench heads and some actions may work with certain models. We will update the list.
